Aside from Bane's training, what proof do we have of more stuff being filmed and cut?
Sorry for being that guy.

There's definitely a lot of stuff that was left in the editing room. Lee Smith says that they had a lot more footage for Rises than normal.But i dont think that was anything major . Just longer scenes , lots of different setups , probably a lot of action footage . As he said , Nolan didn't want a movie much bigger than the other two. So they probably trimmed the fat of some scenes.
